Answer:
The cell membrane will fold over a substance or particle until it becomes completely enclosed by the membrane
Explanation:
Endocytosis is when a substance or particle from the outside is captured and engulfed by the cell membrane until it is in the inside.
Answer:
Muscles are stimulated by electricity. The effect depends on the intensity of the current and the type of muscle it travels through.
The victim may be unable to let go of the source of the current, making the duration of the contact longer and increasing the severity of the shock.
When a current above 10 mA travels through extensor muscles, it causes a violent spasm. If the muscles affected are the hip extensors that lengthen the limbs away from the body, the victim may be propelled, sometimes many metres away!
Muscles, ligaments and tendons may tear as a result of the sudden contraction caused by an electric shock. Tissue can also be burned if the shock is lasting or the current is high.planation:
Unsaturated fats because of the sugars and fat that comes with it
Abiotic, if I remember correctly.
Answer and explanation:
Antibodies are structures made of four polypeptides, <em><u>two light (L) chains and two heavy (H) chains that join together and form a molecule shaped like a "Y"</u></em>. This structure is possible thanks to the <u>disulfide bonds</u> that bind light chains and heavy chains together. While the stem of the Y is constant and doesn't change ("<em>constant region</em>"), the tips of the Y, composed of 110-130 amino acids and called "<em>the variable region</em>", vary greatly among the different antibodies and are responsible for the high specificity of these molecules.
<u>This is why we could say that the primary structure of this protein is given by disulfide bridges that twist the antibody and allow it to bind to a protein from the flu virus.</u>
